There is a warning from Bethesda that your textures may not run properly if you install to the hard drive.
You should play it just off the disc for now.
You can read more about this in the technical area specifically in the 360 section.

This issue still happens off disc, although not as extreme as install.
but if they put a patch for that, will it be worth it to install?
Yes. Xbox runs quieter plus it doesnt heat up extremely hot like playing off the disc so your xbox will survive for longer, personally it's better. Oh and loading times are reduced.
